RE: Exception while trying to use Secure Conversation

I found the problem... it was this line in the configuration file:
<securityTokenM anager type="Laborator ioContracts.Cus tomUsernameToke nManager,
LaboratorioCont racts"
xmlns:wsse="htt p://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" qname="wsse:Use rnameToken" />

It had old reference (from where i took the example).
But, now i have a new problem... :(
